Get the target mesh alignment tranformation. This is a transformation that is applied to the vertex positions of the target mesh, before we calculate the deltas between the linear skinned mesh and the target mesh. This is useful when you imported target mesh that isn't scaled the same, or perhaps it is rotated 90 degrees over the x axis. The alignment transform is then used to correct this and align both base and target mesh.
The alignment transformation. When set to Identity it will not do anything, which is its default.
